We have never heard “I put too many unions on my plumbing.” When it comes to the initial plumbing, servicing, repair, or replacement of any hardware unions will be your best friend. For a couple extra bucks right off the start, down the line, they will pay for themselves when you only need to replace a foot of plumbing and not all of it.

Slip x Slip

Don’t skimp on unions! Easily take apart plumbing sections or remove sumps and pumps for maintenance with unions. The swivel action of a union allows one to position the angle of the elbow even after the glue dries.

The golden rule of plumbing is that every job takes three trips to the store. While this can be frustrating locally it can be much worse when shopping online. Being short a fitting or two can delay a plumbing project for days. Here are some quick tips to avoid this.

Plan your plumbing on paper

Don't skimp on unions. Unions allow for easy breakdown and maintenance as well as remove the need for precise elbow placement. Use them as often as possible.

When in doubt order extra. We happily accept returns for a full refund (less shipping) on all unused fittings within one month of purchase. A few extra bucks in return shipping is less frustrating than a project delay.

Unions for the winBy Buzzardon 5/17/2018

Unions make servicing your setup a breeze, if you think you have to many think again you always find somewhere you should have put one.

Unions are great and easy connections when you are cleaning or making upgrades to your aquarium systems such as upgrading your sump. Made it real easy with my return lines.easy connections

Perfect for what they are designed for. High quality and much nicer looking than the ugly white ones. I'm very happy I decided to go with these instead.

These unions are a lot nicer than my local hardware stores, and redoing my system I put them everywhere I could fit one and I'm happy I did, makes it so much easier to take apart and add or clean things. What a great product sch 80 is the only way to go..

Well Constructed Union By Brandonon 1/30/2014

These are very well constructed unions. I use them on my sch 80 piping with no problems at all. As a recommendation when installing, install with the gasket facing up (so gravity holds it down) as its been noted that this method provides a slightly better chance of having the bulkhead not leak.

Don't plumb without these!!By MJ's Custom Aquarium Wateron 9/21/2012

If you aren't putting in a true union ball valves, put these in. Don't plumb your system without making places to take it apart for maintenence of the pump or fixing problems that arise. So glad I did

Great valve! So much better than the local hardware store. It's just as they say in the video you'll wish you had put in more. At first I was concerned that they might leak. No worries. Best of all they are made in the USA.

I need replacement O-rings for 1 1/2" Schedule 80 Union and for true union 1 1/2" Cepex ball valve. Can I get them from you? Or where can I order them from.

Hey there,
I'm afraid we don't currently have replacement components available for these fittings and only have complete union and ball valve assemblies. My initial search did not turn up any resources for replacement o rings specifically for these products, though it may be possible to buy a third party o ring which would fit. You could also try reaching out to the manufacturer directly to see if they have them available.
